Answer 1

2(x-3)(4x^2+18x+27)

Answer 2

knowing that 3 is a zero, you can divide the whole equation by x-3
then solve for other zeros

Answer 3

just use the quadratic formula to factor it further

Answer 4

ONe root is -3/2

Answer 5

do you know how to use the quadratic formula?

Answer 6

to find the roots of 4x^2+18x+27

Answer 7

3 is definitely not a zero

Answer 8

i would still use synthetic division, however

Answer 9

I like synthetic division too, but i have many solutions to test.

Answer 10

you factored that incorrectly
